The daughter of Fahn. As a child, King Fahn surrendered her to one of the tribes of the desert (which would later become Flaim) to the north, so that she could be sacrificed to Shooting Star to appease the dragon. Parn's father, Tessius, made a secret plan with King Fahn to rescue Fianna, in which he would take all the blame for destroying diplomatic relations with the tribe. This led to his dishonor, and he was sent to the front lines of the civil war that began as a result, where he died.

Fianna's presence is a diplomatic one at first, sent to give a message to Alania, but she is intercepted by Karla who informs her that Alania has fallen anyway. She is saved by Parn and his companions, and later on grants Parn the blade of her father.

Upon first encountering the group, Fianna becomes attracted to Etoh. While it is never explicitly indicated in either the manga or the anime series, it is likely that they were married when Etoh assumed the throne of Valis. Fianna was not considered an heir to the throne, however, as the royalty of Valis is chosen not by royal bloodline, but upon the death of the previous king, a successor is chosen from the knighthood. Etoh's succession to the throne after marrying Fianna was due to his high spiritual power as a Falis priest and the high regard that the church held him in, though there was opposition in not only a non-knight ascending the throne, but Fianna gaining political power as queen.
